Intially I couldn't see how you got angle 1 + angle 6 to be 90.....but I got to open my eyes to see the bigger picture. Good explanation.
Definitely agree with C.

it is C:
(1) <R + <T = 90 in which:

(2) <R = 180 - <RQS - <RSQ = 180 - 2<RSQ (as RQ = RS)
(3) <T = 180 - <UST - <SUT = 180 - 2<UST ( as ST = TU)

(1) + (2) + (3):
180 - 2<RSQ + 180 - 2<UST = 90
=>360 - 2(<RSQ + <UST) = 90
=> 360 - 2 (180 -x) = 90
=> x= 45
